GAS-LAMP.

SPECIFICATION forming part of Letters Patent No. 327.089, dated September 29, 1885.

Application filed July I, 1885. (No model.)

lowing to be a full, clear, and exact descrip tion thereof.

Myinvention relates to the class of gas or vapor lamps; and my invention consists in an oil-reservoir having an outer chamber to which the oil is fed and an inner chamber communicating with the outer one, a peculiar burner communicating with the outer chamber", a rotating fan within the inner chamber above the oil and operated by an electric current, a valved port communicating with the inner chamber, whereby air is drawn in by the fan, and in various details of construction, allof which I shall hereinafter fully. explain.

The object ofmy invention is to provide an effective lamp for burning the gases or vapors originating from gasoline and other liquid hydrocarbons.

Referring to the accompanying drawings,

Figure l is a vertical section of my gas-lamp,

one portion of the reservoir being in elevation and broken away. Fig. 2 -is a portion of a horizontal section through the reservoir R and fan.

1% is an oil-reservoir, in which is formed an is screwed. This burner is made of a central or inner open-ended pipe, d, for ventilation, and one or more encircling or outer pipes, d, which are so formed as to leave a larger annular chamber or space, d, below, and a smaller annular chamber or space, d, above.

E is the burner-key in the hollow stem 6 of the burner, which said stem communicates at one end with the short pipe 0, and at the other with the larger chamber or space (V.

F is the cap-plate or top of the reservoir R.

Through its center is a port, f, controlled by a va1ve,f, the upper portion of whose stem f -is guided by a crossbar, G, and its lower portion, extending downwardlyinto the chamber B, carries the fan H, so that said stem forms the fan-shaft. The point or foot of the stem f is stepped in the upper end of a screw, I, passing through a threaded socket in the bottom of the reservoir, and vertically adjusted by means of a small crank, J below.

Upon the cap-plate or top F is the electromagnet L, the cores Z of which pass down through the plate;

M M are the circuit-Wires of the magnet, to be connected with a battery and arranged so that the circuit will be closed and opened by the vertically-moving valve. Upon the fan are the armaturesN of the magnets, arranged, as shown, in a manner to effect the rotation of the fan when the circuit is closed by the upward adjustment ofthe screw Lwhich elevates the valvefinto contact with one of the circuitwires. This adjustment at the same time opens the port f.

Secured to the fanblades are the downwardlyextending arms or agitators O. The top of valvef is a cam,- so that the electric contact is momentarily broken to effect the rotation of the fan.

The operation of the lamp is as follows: Gasoline or other suitable liquid hydrocarbon is supplied to the chamber A through aperture a, and it rises in both chambers A and B to the level of the base of the supply-aperture, which is so located that the fan H is just above the level ofthe oil. The screw I is set up to raise the valve f slightly and close the electric circuit, and at the same time,by raising said valve, to open the 'portf. The fan is rotated by the action of the electric current, whereby the air is drawn in through theppen port f,and forced by the fan through the aperture 1) into chamber A. This air travels around nearly the whole 5 circumference ofchamber A, mixingthoroughly with the gasoline, and the vapors ascend through tube 0 and into the burner. Here the gas collects in the lower and larger chamber, (1 and feeds the flame in sufficient quantities at the top of the upper and smaller chamber,

The agitators 0 keep the, oil in motion, and tend to. a more thorOugh mixture of air and gasoline.

It will be observed, Fig. 2, that though the aperture 1), through which the air passes into the chamber A, is near the exit-tube 0 of said chamber, it is not directly in communication therewith, so that the air has to pass around nearly the entire circumference ofthe chamber A before reaching the exit. This is for the purpose of causing itto mix thoroughly with the gasoline.

The object of the larger chamber (1 in the base of the burner is to provide for an accumulation of gas to keep up the combustion above. I have found that if the chamber in the burner is the same size all the way down the feed is not regular or constant; but by accumulating in the lower chamber the flame is steady.

To turn off the light, the keyE is used, and to throw the lamp completely out of operation the screw I is lowered, whereby the fan drops down and opens the circuit, and at the same time the valvef closes the portf.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

'1. In a gas-lamp, the combination of an oil chamber or reservoir,a burner communicating therewith, a rotating fan, suitable armatures on the fan, and an electro-magnet for operating the fan, substantially as and for the purpose described.

2. In a gas-lamp, the combination of the oil-reservoir R, having an outer chamber, A, and an inner chamber, B, with a communicating aperture, 1), a burner, a pipe communicating with the burner and with theouter chamber, A, the latter communication or eXit being as far as possible from the aperture or entrance between the two chambers, and a rotating fan in the inner chamber above the oil, substantially as herein described.

3 In a gas-lamp, the combination of the oilreservoir It, having an outer chamber,A,with a supply-aperture, and an inner chamber, B, with an aperture communicating with chamber A, a burner communicating with the outer chamber, arotating fan in the inner chamber above the oil, and a valved port in the top of the reservoir through which the air is drawn by the rotating fan, substantially as described.

4. In a gas-lamp, the combination of the oil-reservoir R, having a port, f, an inner chamber, B, with which the port communicates, and an outer chamber, A, communicating with chamber B, a burner communicating with the outer chamber, a vertically-moving valve controlling the port f, having stem f, the fan 11 on the stem, and the vertically-adjnstable screw I through the bottom of the reservoir, in which the valvestem is stepped, substantially as described.

5. In a gas-lamp, the combination of the oil-reservoir R, having an outer chamber, A, with asupply aperture,and an inner chamber, B, having an aperture,b, communicating with chamber A, a burner communicating with the outer chamber, the fan H in the inner cham' her, and the mechanism for rotating said fan, consisting of the electro-magnet L on the reservoir, an electric circuit including the magnet, and the armatures N on the fan, substantially as described.

6. In a gas-lamp, the combination of the oil-reservoir R, having an outer chamber, A, with a. supply-aperture, and an inner chamber, B, having an aperture,b, communicating with chamber A, and a top port, f, a burner communicating with the outer chamber, the valvef, controlling the port and having stem f, the fan H on the stem, the adjusting-screw I, in which the stem is stepped, the electromagnet L in a battery circuit closed and opened by the valve, and the armatures N on the fan, all arranged and adapted to operate substantially as herein described.

7. In a gaslamp, the combination of the oil-reservoir R, having concentric communieating chambers A and B, the supportingbracket 0, one a-rm,c, of which is tubular and communicates with chamber A,the burner D, supported from the bracket and communicating with the tubular arm 0, and the rotating fan H in chamber B above the oil,sub stantially as described.

8. In a gas-lamp, the combination of the oil-reservoir B, the burner D, communicating therewith, the rotating fan in the reservoir above the oil, and adapted to draw in air and force it into the oil, and the agitator-arms O on the fan extending down into the oil, substantially as herein described.

9. A gas-lamp comprising the reservoir R, having concentric communicating chambers A B, the burner D, communicating by pipe 0 with the chamber A, the vertically-adjustable valvef, controlling an air-port in the top of chamber B, the rotating fan H on the valves'te'm and above the oil in chamber B, the agitatorarms on said fan and extending into the oil, the electro-magnet L, and circuit-wires on the reservoir, and the armatures N on the fan, whereby it is rotated, substantially as described.
